Father, Glen Greenwood and the family's eldest daughter, Hannah Greenwood, 10, survived the crash. Both are recovering from serious injuries.

The family is now asking the public for help in piecing together what happened on the morning of the pileup.

Monforton said, "our law firm has been retained to investigate and prosecute civil claims against those responsible for this horrible tragedy. The family is suffering unspeakable pain and has asked us to thank the media and the public for respecting their privacy at this time."

Witnesses can contact Monforton at 519-258-6490 or his U.S. co-counsel Robert Darling at 248-880-0180.
